| int(* AVInputFormat::read_probe)(AVProbeData *) |
tell if a given file has a chance of being parsed by this format.
The buffer provided is guranteed to be AVPROBE_PADDING_SIZE bytes big so you dont have to check for that unless you need more.
Referenced by av_probe_input_format2().
| int(* AVInputFormat::read_header)(struct AVFormatContext *, AVFormatParameters *ap) |
read the format header and initialize the AVFormatContext structure.
Return 0 if OK. 'ap' if non NULL contains additional paramters. Only used in raw format right now. 'av_new_stream' should be called to create new streams.
Referenced by av_open_input_stream().
| int(* AVInputFormat::read_packet)(struct AVFormatContext *, AVPacket *pkt) |
read one packet and put it in 'pkt'.
pts and flags are also set. 'av_new_stream' can be called only if the flag AVFMTCTX_NOHEADER is used.
Referenced by av_read_packet().
| int(* AVInputFormat::read_close)(struct AVFormatContext *) |
close the stream.
The AVFormatContext and AVStreams are not freed by this function
Referenced by av_close_input_file().
| int(* AVInputFormat::read_seek)(struct AVFormatContext *, int stream_index, int64_t timestamp, int flags) |
seek to a given timestamp relative to the frames in stream component stream_index
| stream_index | must not be -1 | |
| flags | selects which direction should be preferred if no exact match is available |

| const char* AVInputFormat::extensions |
if extensions are defined, then no probe is done.
You should usually not use extension format guessing because it is not reliable enough
